兴趣是指人们为了满足自己求知欲望而对某种事物或某种活动进行积极探索的一种认识倾向。兴趣能激发大脑皮层使其到达兴奋状态。因此,教师应该从学生的兴趣着手,使兴趣成为学生参与科学实践、学习科学知识的强大鞭策力。初中化学课程具有涉及范围广、涵盖内容丰富、接触知识复杂的特点,所以要想在有限的时间内使学生熟练地掌握、理解和吸收所学的化学知识是具有相当的难度的。因而,实施趣味教学法培养学生的兴趣,使学生在潜移默化中产生对学习的兴趣是现代教育的当务之急。 Interest is the tendency of people to actively explore something or some kind of activity in order to satisfy their desire for knowledge. Interest can stimulate the cerebral cortex to reach the excited state. Therefore, teachers should start from students’ interest and make interest become a powerful stimulus for students to participate in scientific practice and learn scientific knowledge. The junior high school chemistry curriculum has the characteristics of wide scope, rich content and complex contact knowledge. Therefore, it is quite difficult for the students to master, understand and absorb the learned chemistry knowledge in a limited time. Therefore, the implementation of interest teaching method to cultivate students’ interest in making students interested in learning in the subtle is the top priority of modern education.
